Physiology Analysis
AS Huffmyer
Script to analyze larval size, symbiont density, and examine correlations between physiological responses.
Setup
Set up workspace, set options, and load required packages.
knitr::opts_chunk$set(echo = TRUE, warning = FALSE, message = FALSE)1. Larval Volume
Volume is calculated as an elliptical sphere using the length and width measurements of each individual.

Data manipulation and correlation
First, test for correlation between symbiont cell density and larval volume to see if there is a relationship.
Generate data frame with summarized size and cell density information for each time point from eggs to metamorphosed recruits, because we have data for volume and counts for each sample. We do not include attached recruits here yet, because we cannot calculate densities per individual.
